Hello, all! First post here. I just bought a Jurca 3/4 P-51 restoration project which includes a Geschwender PSRU mated to a small block Ford 400 engine. The PSRU is geared at 2.66:1, and I am wondering why it is geared so high. It seems this would require quite high engine RPM at cruise which would shorten TBO and even lead to failures. The Ford 400 is mainly a truck engine and provides good low RPM torque, but with this PSRU it seems the required engine RPM would be too high to take advantage of that. Any ideas? Am I missing something? Thanks!
